The Cellar - MIT OpenCourseWare Offers Free Downloads of Course Materials

MIT OpenCourseWare offers free downloads of course syllabuses, lecture notes, exam questions, etc.

In theory you could buy the textbooks and audit the classes for free.

They even have translations of some classes.

Today, MIT OCW is a large-scale, Web-based publication of the educational materials from the MIT faculty's courses. This unique initiative enables the open sharing of the MIT faculty's teaching materials with educators, enrolled students, and self-learners around the world. MIT OCW provides users with open access to the syllabi, lecture notes, course calendars, problem sets and solutions, exams, reading lists, even a selection of video lectures, from 1550 MIT courses representing 34 departments and all five of MIT's schools. The initiative will include materials from virutally all courses by the year 2008.
